How do I call a string method twice in Java without repeating the whole method?
问题
import java.util.Scanner;public class firstLastName2 {static String F_NAME;static String L_NAME;static String name;static void firstName(String name) {Scanner keyboard = new Scanner(System.in);System.out.println("Please enter your first name.");F_NAME = keyboard.nextLine();System.out.println("Please enter your last name.");L_NAME = keyboard.nextLine();}public static void main(String[] args) {firstName(name);System.out.println("Hello, " + F_NAME + " " + L_NAME + "!");}}

What I am trying to do is prompt a user to enter their first and last name by calling a function twice. First call would be for the first name and the second call would be for the last name. The program would then concatenate and display "Hello, firstname lastname!" I feel like I am very close to the correct outcome but I am obviously missing something. New guy here. Thank you for any and all responses.
import java.util.Scanner;public class firstLastName2 {static String F_NAME;static String L_NAME;static String name;static void firstName(String name) {Scanner keyboard = new Scanner(System.in);System.out.println("Please enter your first name.");F_NAME = keyboard.nextLine();System.out.println("Please enter your last name.");L_NAME = keyboard.nextLine();}public static void main(String[] args) {firstName(name);System.out.println("Hello, " + F_NAME + " " + L_NAME + "!");}}

如果您想要调用一个函数两次，那么我建议该函数返回用户输入并接收问题文本。您的代码似乎是正确的。import java.util.Scanner;public class firstLastName2 {static Scanner keyboard = new Scanner(System.in);static String getUserInput(String question) {System.out.println(question);return keyboard.nextLine();}public static void main(String[] args) {String name = getUserInput("请输入您的名字：");String surName = getUserInput("请输入您的姓氏：");System.out.println(String.format("你好，%s %s！", name , surName));}}

If you want to call a function twice, then i suggest that the function return the user input and receive the question text. Your code seem to be right.
import java.util.Scanner;public class firstLastName2 {static Scanner keyboard = new Scanner(System.in);static String getUserInput(String question) {System.out.println(question);return keyboard.nextLine();}public static void main(String[] args) {String name = getUserInput("Please enter your first name.");String sunrName = getUserInput("Please enter your last name.");System.out.println(String.format("Hello, %s %s!", name , surName));}}
